Fodor's Expert Review Las Médulas

One of northern Spain's most impressive archaeological sites, this mountainous area of former Roman gold mines—located 24 km (15 miles) south of town—is a UNESCO World Heritage Site. The landscape is the result of an ancient mining technique in which myriad water tunnels were burrowed into a mountain, causing it to collapse. Miners would then sift through the rubble for gold. What's left at Las Médulas are half-collapsed mountains of golden clay with exposed tunnels peeking through lush green forest. Take in the best panorama from the Orellán viewpoint. There are hiking paths, a small archaeology exhibit, and a visitor center; the latter organizes 3-km (2-mile) walking tours—check schedules online, and call or email ahead to book ( [email protected]). A parking lot was added in 2021; the price is €3 per vehicle.
